Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Car glass cleaning is very important in rainy weather

The cleaning of car windows is not only an issue of appearance, but also a necessity in terms of safety. Especially on rainy nights, the dazzling oil film will affect the field of vision and must be removed immediately. If it is slightly dirty, you can wipe it with a towel and car without using a car body cleaner. You can wipe it off immediately or remove the oil film. After the dirt is completely removed, apply a protective agent, which can make the oil film difficult to adhere.

1. Dirty car windows threaten safety. When driving at night on rainy days, the wiper wiped off and the residual oil film is dazzling, which greatly affects the vision.

2. Thoroughly clean the windows of the car, the vision is immediately clear, and it is easier and safer to drive at night.

3. If the oil film attached to the glass is difficult to remove by ordinary methods, use a chemical synthetic agent for removing the oil film to wipe it.

4. Not only the outside, but also the interior of the glass must be wiped. The insulation line must be wiped horizontally. If it is wiped vertically, the insulation line may be broken.

5. A car window protectant that can effectively prevent dirt and oil film from adhering to the glass surface. But before use, you must clean the car windows, otherwise it will be difficult to have an effect.

6. After the protective agent dries, it will turn white just like waxing. Just wipe it off with a soft cloth.

7. After the protective agent is applied, the water will roll off in granular form. If the rain is not heavy, you don’t even need to activate the wiper.

8. There are also protective agents added to the water tank. Just clean the windshield before use, otherwise the effect will not be good.
